Effect of soil-structure interaction on the seismic behaviour of pedestal-structure system in large dish antennas

Regarding the progressive improvement in the territory of Space Technology in all developed countries and consequently developing countries including Islamic Republic of Iran, the optimization of design and utilization of the communication equipment has been paid more attention today. For instance,...
